Which occasion is designated for reporting marks on active duty Marines?

The designated occasion for reporting marks on active duty Marines is semiannual. This means that performance evaluations are conducted twice a year, allowing for a comprehensive assessment of a Marine's skills, accomplishments, and overall conduct. The semiannual reporting period strikes a balance between providing enough time to observe performance trends and ensuring that evaluations remain timely and relevant.

Additionally, evaluating Marines on a semiannual basis allows for the opportunity to address areas of improvement within a suitable timeframe, promoting professional growth and development. Regular performance evaluations are crucial in maintaining unit readiness and ensuring all Marines are held to the standards expected of them.
